Answer:

$0.22 -1 *0.029 =0.191$

$0.22 +1 *0.029 =0.249$

And the best option would be:

D. (0.191 to 0.249)

Step-by-step explanation:

For this case we know that the mean is:

$\bar X = 0.22$

And the standard error is given by:

$SE = 0.029$

We want to construct a 68% confidence interval so then the significance level would be :

$\alpha=1-0.68 = 0.32$ and $\alpha/2 =0.16$ . The confidence interval is given by:

$\bar X \pm z_{\alpha/2} SE$

Now we can find the critical value using the normal standard distribution and we got looking for a quantile who accumulate 0.16 of the area on each tail and we got:

$z_{\alpha/2}= 1$

And replacing we got:

$0.22 -1 *0.029 =0.191$

$0.22 +1 *0.029 =0.249$

And the best option would be:

D. (0.191 to 0.249)

Factor Trinomials (a=1) factor x^2-10x+16

dem82 [27]

Answer:

(x-8)(x-2)

Step-by-step explanation:

factors of 16:

1 x 16

2 x 8

4 x 4

i'll select 2 and 8 as values because they can add up to 10

(x-8)(x-2)

i made them both negative so the middle term would be -10 but, when multiplied, would equal positive 16
